Asfare i can see the addon is nice to use, only thing i do not understand is de colouring of the resipes i do not have, like : gray, red and orange...

Maybe and thats what the red is, is you need to have an reputation with an faction, like Timbermaw Hold, where i'm Exalted with, and still the resipe is red, can you check the stats of an character to see wather he/she is already passed the point where you can get an resipe, and colour it green (or blue becouse green is the colour of Trainers) if you can get it, instead of red.

Coloring recipes is a good idea, however, I use TSI (just an awesome tool and better than asking others for info) and it already does this. I selected "Add info to mob tooltips informing you what recipes that mob drops" as that would be very useful when I'm wandering around and notice a particular mob drops something I don't already have so I may grind if need be.

1) Coloring of recipes based on which ones are known/unknown. Make sure this is configurable, please. All I want here is a simple red alpha map overlay or outline around the icon when the current toon already knows the recipe, but I know others want it for alt's or not at all.

2) Better ways to datamine recipes of other professions. The ARL -> Filter -> Misc -> Alt thing is very cumbersome especially if you haven't learned the recipe you are looking for on your alt. Plus if none of your alts knows the profession you want, you have to resort to the Interface Options -> ARL Options -> Datamine button which a) doesn't have all tradeskills and b) is still too complex. You should be able to just go into ARL's filter area and "switch" the current ARL window to a full listing of everything for any profession.

Be able to filter or color displayed recipies based on whether any of my toons show via altoholic / mouseover that I have any of the output.

If I am re-stocking glyphs, would be very nice only to see the list of glyphs that I need to make, so I don't need to go through the entire list and mouseover each one to see if I am out of that glyph.

my situation my be unique and (perhaps) unsupportable, but, i have multiple accounts and it would be a blessing if there were some way to track across the three accounts, even if I had to manipulate it by hand. My current procedure is to greed on the enchant then mail it to the second account to check if any toon can use, then mail to the third. maybe a giant Ackis clearing house of some kind? Using the Coloring system option is also be helpful.
